I MEANS FOROPERATINGWHEQGEES'fiF A BOARD DROP-HAMMER.

Application filed June 26, 1916. Serial No. 105,871.

To all whom it may concern:

Be it known that I, HOWARD TERHUNE, a citizen of the United States, and a resident of Chambersburg, in the county of Franklin and State of Pennsylvania, have invented.

certain new and useful Improvements in invention is to furnish an improved housing for, carrying the board operatin rolls of a drop hammer the several parts 0 which will be reduced to their simplest form and which will be so constructed that it may be quickly taken down to permit the instant removal of the shafts and rolls or other parts which may need attentionor repairs.

My invention is illustrated in the accompanying drawings in which similar letters of reference indicate similar parts throughout the several views, and in which- Figure 1, is a side elevation of the'housing carrying the shafts and rolls of a board drop hammer, and

Fig. 2, a front elevation, partly in section, of Fig. 1.

3-4 are the driving pulleys for actuating the shafts 5-6 which carry the rolls 7-8 of a board drop hammer. 9 is the board which is attached to the ram, and 10-11 the housings which inclose the rolls which operate to elevate the board and in which are formed the bearings for the shafts of said rolls.

Heretofo-re, as far as I am advised, it has been the practice to cast the holder or housing which carries the board elevating roll,

its shaft, etc., in onepiece and it has often been very diflicult to remove the shaft from a roller while in the housing for the shaft and its roll must necessarily fit closely and these/parts is the duplicate of the other but one will b d s ribed, and this inventi n Specification of Letters Patent. Patented N 13, 1917,

has to do with the roll carrying housings 7 only, no attempt will be made todescribe the means whereby the rolls; are operated to engage and disengage the board.

My rolls 7-8 are secured to or cast with their shafts 5-6 concentrically and, as

usual, rotate in opposite directions. The housings for the rolls and shafts are split at right angles to the shafts forming two sepapreferably, furnished with a tongue and groove 13 in order that their alinement may 7 be insured when they are bolted together.

In the drawings the housing is shown split in the middle but, of course, this splitting maybe nearer one end than the other, or otherwise, as may be found most convenient for the purposes intended.

It will be evident that my housing for the roll carries with it extensions which are inclosed within outer bearings for adjust-- Having thus described my invention, I

claim as new and desire to secure by Letters Patent v 1. A housing for an elevating roll and its shaft for a board drop hammer, comprising two parts abut-ting in a plane at rlght angles to the roll carrying shaft and bearing members for board gripping adjustment purposes inclosing the ends of the housing.

2. A housing for an elevating roll audits shaft for a board drop hammer, carrying a one of the cooperating members for adjust ment of the roll toward and from the board and a bearing for the roll shaft, and c0m-- prising two parts abutting ina plane at right angles to the roll carrying shaft.

8. A housing for an elevating roll inclos ing both the roll and its shaft, providing bearings for opposite ends of the roll shaft and transversely divided into two parts be-I tween these bearings.

4. A housing for an elevating roll and its shaft for a board drop hammer, comprising, V a pair of bearings, one for each end of the shaft and a casing for the roll of largerv diameter than said bearings and trans:

so rate pieces 11 and 12 and these pieces are, V

versely to the shaft in this larger diameter a connecting roll cover transversely divided portion of the housing and cooperating and interfitting at the point of division.
